Miyota 9015
Introduced in 2009, the Miyota 9015 was the company's first entirely new mechanical caliber in roughly 30 years and sits at the top of their 9000 series — a deliberate step up from the older 8215. Miyota (a subsidiary of the Citizen Watch Group) designed it from the ground up as a premium in-house offering rather than a derivative of an existing architecture, with a notably slim 3.9 mm profile, 28,800 bph beat rate, hacking seconds, and clockwise hand-winding.
In the broader mid-range automatic market the 9015 competes directly with the ETA 2824-2 and Sellita SW200-1, offering comparable beat rate and functionality at a significantly lower price point. Its thin height and reliable specifications made it a go-to choice for a large number of independent microbrands and smaller established houses seeking a capable movement without the supply restrictions and cost of Swiss alternatives.
A cosmetic variant exists with a gold-toned finish but shares identical mechanical specifications to the standard 9015; Miyota does not offer named performance grades for this caliber. The rotor winds via a ball-bearing system, and the shock protection system is Miyota's own Parashock design.

FAQ
Is the Miyota 9015 automatic or manual?
The Miyota 9015 is an automatic (self-winding) movement: a rotor winds the mainspring from the motion of your wrist, so it needs no battery. It can also be wound by hand via the crown.
What is the power reserve of the Miyota 9015?
About 42 hours on a full wind — into a second day, so it keeps running overnight off the wrist. Power reserve is how long the Miyota 9015 keeps running once you stop wearing or winding it.
Does the Miyota 9015 hack (stop the seconds when you set it)?
Yes. Pulling the crown stops the seconds hand, so the Miyota 9015 can be set precisely to a reference time before you push the crown back in. Hacking is what lets you sync several watches — or a watch and a phone — to the exact second.
Does the Miyota 9015 have a date function?
Yes — the Miyota 9015 can drive a date display, though whether a given watch actually shows the date depends on the dial the maker chose, so check the individual model rather than the movement.
How accurate is the Miyota 9015?
The Miyota 9015 is rated at -10/+30 s/day. That is a normal working range for an uncertified mechanical movement; a COSC-certified chronometer is held to a tighter −4/+6 s/day, and a watchmaker can usually regulate one closer. Real-world accuracy still depends on how each watch is regulated, worn, and serviced.
